I would like to setup 3 external HD (USB) as backup tapes.
What should be done to setup this setting?
First read:

When choosing a filesystem, formatting them with ext3 is just fine.
Many of them come preformatted with NTFS -- unusable under Linux.
If the drives need to be shared with a PC, then vfat is an option
too (but then you need also use Amanda 2.5.0 with tape-splitting
feature to avoid bumping into the 4 Gbyte filesize limit of vfat).
I could add something more about how to rotate 2 or 3 external disks
using the scheme there.
I can think of two ways:
Each of the disks contains e.g. 7 slots (let's you rotate them
one each week):
- disk 1: slot1 .. slot7
- disk 2: slot8 .. slot14
- disk 3: slot15 .. slot21
Mount the disks (can be done automatically) under /media/amandavtapes,
so that the slots can be found as /media/amandavtapes/slot1 etc.
When using chg-disk, you have to create the vtape tree on the
internal hard disk, but instead of creating subdirectories named "slot1"
you make them soft links to /media/amandavtapes/slot1 etc.
Chg-disk uses a softlink "data" pointing to the current slot too. So
this means that amanda follows two symlinks now to get to the external
disk.
When using chg-multi, you can set up the /media/amandavtapes/slotX
immediately in the chg-multi.conf file.
